Chile's benchmark IPSA index climbed 0.53% to close at 10,763 on June 26, extending a two-day winning streak.
The advance was driven by a rebound in copper prices, which provided immediate tailwinds for the mining heavyweights that dominate the Santiago exchange.
The local currency also provided support, holding steady against the dollar and reducing currency headwinds for export-oriented firms.
The market move follows a period of volatility for the index.
On Thursday, the IPSA had posted a modest 0.29% gain to 10,706, ending a brief two-day losing streak.
That earlier recovery was attributed to a shift in global sentiment following softer-than-expected US inflation data.
